So your argument is that The Universe and it's orderly laws that govern it are completely random and that The Universe was born through The Miracle of the entire mass of The Universe fitting into the size of a pinhead and then some miraculous Big Bang happened for no reason at all?
If the gravity compressing The Universe's Original Mass was able to contract it, restrain it, and compress it into the size of a pin head before The Big Bang, then such gravity would be unable to be overcome by any force. If The Universe did explode in such a circumstance, such gravitational force would still exist, and The Universe would contract again towards it's original source point.
We don't see that. What we see is an orderly expanding universe that is more light years wide than scientists say it's age is. Again, they can't explain that, nor explain how The Universe is able to overcome the gravity of it's original source point.
It's just nonsense conjecture designed to cut God out of the picture with regards to intelligent design. Same goes for Evolution nonsense, and Global Warming nonsense.
